Replace the usernames, hostname and password according to your specific environment. Load the babel tables and sample data (the root account is used here, as the 'babel' account doesn't have CREATE/DROP privileges):

mysql -u root -p babel < /path/to/babel/server/babel-setup.sql

The first time you'll run the Babel setup script, you will get an error from occurring for a trigger that does not exist.

To avoid this error, install MySQL version >= 5.0.32 or version >= 5.1.14 to be able to use IF EXISTS clause for DROP TRIGGER statement and modify the Babel sql script:

Replace: DROP TRIGGER `ins_version`;

by: DROP TRIGGER IF EXISTS `ins_version`;

Requirements for PHP

PHP must have the ability to encode data in the JSON format. As of PHP 5.2 'json_encode' and 'json_decode' are included by default. If you are using an earlier version you will need to install the JSON PECL extension, find another json_encode library or write your own json_encode function. See this page to find out more information on JSON and PHP.

Install Phoenix

Currently, Eclipse Phoenix code is required for Babel Server to run. There are plans to fix this (bug 217488). The Phoenix code must be installed in html/ with a symbolic link to it in your Apache DocumentRoot.

Before checkout Eclipse Phoenix code, you should delete the CVS folder for eclipse.org-common located here /path/to/babel/server/html/eclipse.org-common/CVS as it corresponds to the Eclipse Babel code CVS configuration (eclipse.org-common and its subfolders are checkout during Eclipse Babel code checkout)

Logging in, load strings from dev.eclipse.org CVS

Creating (building) a language pack

To create a language pack, simply run php5 path/to/generate1.php from a command line (or from cron). This requires many Linux commands to be found in the PATH environment variable; notably, the jar command that is included with most JDKs.

Submitting code patches

Server code patches must be attached to Bugzilla bugs and enhancement requests. Please ensure patches are submitted against a recently updated HEAD stream. Look for org.eclipse.babel/server in:

:pserver:anonymous@dev.eclipse.org:/cvsroot/technology

Submitting database changes

Database versioning is something we are working on for the next Milestone release (Milestone 1). Currently if you want to make changes to the live database you need to put the SQL queries for alter/insert/update/create into the schema_change.sql file. When the next tagged version of the code is released the web master will process the schema_change.sql file by hand and make the appropriate changes to the database and test files.

Release process

Tag the CVS code with a release tag: R_x_YYYYMMDDHHMM, where x is the release number and YYYYMMDDHHMM is the local time of the tag.

Send an email to babel-dev@eclipse.org to announce the request for a deployment, specifying the release tag.

The Designated Deployment Drone (currently Denis) then establishes an SSH connection to the Babel server, and as the deployment user 'genie', runs the ./deployBabelLive.sh <rtag> to deploy the release.

Data Bridges

The Babel server has two data bridges:

Eclipse Bugzilla: this bridge is used to maintain a mapping of the Bugzilla user accounts on the Babel server. A process on the Bugzilla server and on the Babel server monitors this URL for changes, triggering an export (and an import) of the data.

Eclipse Project/Version info: When the Bugzilla bridge is run, the Project/Version info is pulled from this URL.
